Senior Mobile Engineer / Tech Lead (Kotlin Multiplatform & Native iOS/Android) Position Type: Contract (to hire) Location: Downtown Toronto, ON (Hybrid) About the Opportunity We are seeking a Senior Mobile Engineer trending toward Tech Lead to join a flagship engineering organization building mission-critical mobile platforms.

This team serves as the core technical delivery engine for high-scale, cross-platform mobile applications supporting million of active users and high-volume digital transactions across North America.

You will step into a hands-on, high-ownership engineering environment where you will write clean, production-grade code while stepping up to provide technical guidance, code reviews, and architectural leadership across modern mobile applications.

Key Responsibilities - Hands-on Development: Design, build, test, and maintain high-performance, secure mobile applications leveraging Kotlin Multiplatform (KMP) alongside native Android (Jetpack Compose) and iOS (Swift) architectures. - Architecture & Modernization: Steer cross-platform code-sharing initiatives without sacrificing native performance, device-specific UI fidelity, or strict platform security standards. - Technical Leadership & Mentorship: Act as the primary technical sounding board within the squad—conducting thorough peer code reviews, establishing clean coding conventions, untangling complex architectural blockers, and mentoring engineers. - Enterprise Integration: Interface with modern cloud data layers, distributed backend APIs, and enterprise identity/authentication frameworks. - Quality & Reliability: Drive comprehensive automated testing, CI/CD pipeline automation, and performance profiling to ensure zero regression across production-grade transactional platforms.

Required Technical Qualifications & Experience - 7+ years of professional software engineering experience, with deep,



specialized production experience building and deploying consumer- or enterprise-facing mobile applications. - Hands-on Multiplatform & Native Depth: * Demonstrated mastery of Kotlin Multiplatform (KMP) for business logic and data-layer sharing. * Deep native Android expertise using modern architecture and Jetpack Compose. * Strong working proficiency in native iOS development using modern Swift and native UI frameworks. - Architecture & Patterns: Solid understanding of Clean Architecture, MVI/MVVM design patterns, coroutines/flows, reactive programming, and modular application design. - Security & Performance: Proven track record dealing with complex mobile challenges (data caching, memory leaks, high-frequency state management, API latency, and enterprise-grade mobile security standards). - Leadership Readiness: Demonstrated capacity or strong desire to step into a Tech Lead capacity; possessing the communication maturity to align technical direction with product managers and business stakeholders without hand-holding.

Cultural & Engagement Details - Production Capability over Resume Buzzwords: We look for genuine architectural depth and hands-on execution.

You know how to diagnose low-level concurrency issues and performance bottlenecks in production apps, not just build sample tutorial apps. - High Accountability & Ownership: Punctual, collaborative, direct, and ego-free.

You take pride in robust code, explicit documentation, and building a supportive team environment. - Engagement Term & Future Outlook: This engagement begins as an initial 6-month contract; after 6 months, if there is mutual alignment on performance and organizational fit, the team is actively looking to discuss a transition to a permanent full-time position. - Work Arrangement: Must be able to work on-site at the downtown Toronto office 3 days per week minimum (core team days in-office).

Fully verified professional references are required prior to start.
